ABSTRACT:
A method for treating a nail in order to increase the withdrawal load required to withdraw the nail from a piece of timber into which it has been driven. In accordance with the invention the nail is coated with a suspension containing a chelating agent so selected that, upon contact with lignin present in the timber the nail is bonded to the lignin via a chelate bond. The chelating agent comprises a modified polysaccharide in aqueous solution and is provided with a protective colloid to which the chelating agent has a lower affinity than to the lignin present in the timber. The suspension also includes a suspended polymeric thermoplastic resin to which the chelating agent has a lower affinity than to the protective colloid.
